PCMark Vantage - Drives with Data Testing
For a complete breakdown on the Drives with Data Testing please read this article. You will be able to perform this test at home with the files provided in the article - full instructions are included.
SSDs perform differently when used for a period of time and when data is already present on the drive. The purpose of the Drives with Data testing is to show how a drive performs in these 'dirty' states. SSDs also need time to recover, either with TRIM or onboard garbage collection methods.
Drives with Data Testing - 25%, 50%, 75% Full States and Dirty / Empty Test
Files needed for 60 (64GB), 120 (128GB), 240 (256GB)
60GB Fill - 15GB, 30GB, 45GB
120GB Fill - 30GB, 60GB, 90GB
240GB Fill - 60GB, 120GB, 160GB
Empty but Dirty - a test run just after the fill tests and shows if a drive needs time to recover or if performance is instantly restored.

Until today we haven't published a lot of information on this test and the Crucial m4. The m4 performs really well in our 'out of the box' Vantage test, but once data is added to it the performance drops off....a lot! With the Crucial m4 being the closest competitor to the SandForce SF-2281 products, this information is important to include. I spent a lot of time verifying the data, more than I would normally spend on a set of tests but with results so dynamic and warranted the scrutiny.
With that in mind, let's look at the performance drop off on the OWC Mercury Extreme Pro 6G. The drive scales as data is added, but its lowest point is right around 49000 Marks. This result was measured with the drive 75% full, but it is still faster than the Crucial m4 when just 25% full.
